1 UNITED I Specification;

To all whom may Be it known that L. Samara-e Ewen;

residing at Newton, 11'1" the, county of lVI -iddle sex and State erMassachuse have in} 'vented an Improvement in Oil-Cups, of

which the following is a specification This inventlon. has reference tooil-cups,

and particularly to the closing means there for. The invention has foritsobject to construct an IIDPIOVQCl self-"clos ngdevice for an oil-cupcomprising 'a disk having an annormally closed position, and also havingan ear at the apex of the boss, and a, spring connected atone end tosaid ear which extends lengthwise through the cup and is connected atits opposite end to a cross-bar which is arranged in an annular recessat the bottom of the cup and which admits of a rotary movement of thedisk and spring relative to the cup, so that in case the disk should beturned accidently or otherwise, the spring Will not be unduly strained,and the end connection of the spring with the ear is sufliciently remotefrom the-boss to provide a space therebetween. so that said ear mayengage the edge of the top of the body and rock thereon when the disk istippedto open and close the cuprand toad-- mit of said disk being tippedup into approximately a vertical position to open wide the top of-thecup.

The invention also has for its object, to connect a non-extensible linkwith the spring by which extension of said link is limited, said link,however, being connected with the spring so as to admit of rotation withthe spring and disk whenever the disk is turned- With respect to thecup.

F igure'l is a side elevation of an oil cup embodying this invention.Fig. 2 is a vertical section of the same. Fig. 3 is a view similar toFig. 1, the closing-disk being tipped up into vertical position to openthe cup at the top. Fig. 4. is an under side view.

Saidcross-bar is treeto be turned in said recess, so that in case the diskZ) is turned accidentally or otherwise, the spring will not be undulystrained and its efficiency thereby impaired as would be the case if thelower end of the spring was connected by fixed means to the bottom ofthe cup. than the opening through the body adapting it to be moved intoan inclined position to permit the disk to be tipped up into verticalposition, as shown in F 3, to open the cup at the top, andsaid springacts to im mediately return the disk to normal position as soon as saiddisk is released. The disk when resuming its normal position is centeredby the conical boss so that it becomes properly seated on top of thecup. The upper end connection of the spring with the ear issuflicien'tly remote from the boss to provide a space therebetween sothat said car may engage the edge of the top of the cup and act as afulcrnnrlever when the disk is tipped upwardly to open the top of thecup and to admit of said disk being tipped up into vertical position toopen wide the top of the cup. It will be noted that the distance betweenthe end connection of the spring with the ear and the boss isapproximate]; as great as the thickness of the wall of the tubular bodyand the ear is thus adapted to rock on the edge of the top of the cup.The cross-bar is detachably connected with the spring by reason ofextending through the coils at the lower end thereof, but held in theannular recess by the spring. To prevent the disk from being lifted ortipped up so far as to unduly strain and thereby impair the efficiencyot the spring, a non-extensible link (Z, cont posed, as here shown, ofwire, is provided, which is arranged at the side of the spring, and saidlink is made longer than the spring, and its ends (Z and (Z are bentover to form Said spring is smaller in diameter hooks which extend intothe openings in the opposite ends of the spring, as for instance, saidends d and d may extend through the coils, as represented in Fig. 2.Said link, however, is quite independent of the spring and permits saidspring to be extended, but acts to limit its extension. In case the diskis turned and the spring is turned with it, the link which is connectedat its ends with the spring also will be turned.

I claim The oil-cup herein described consisting of a tubular body, aself-closing disk at the top thereof having on its under side an annularseat to engage the top of said body, and a conical boss arranged withinsaid seat having an ear at its apex, a spring extended through said bodywhich is connected at one end to said ear, and means to rotatablyconnect the other end of said spring with the bod the end connection ofsaid spring with the ear being sufficiently remote from the-boss toprovide a space therebetween to admit of the ear engaging the edge ofthe top of the cup and rocking thereon as the disk is tipped to open andclose the cup, and to admit oi said disk being tipped into a verticalposition to open wide the top of the cup, and a link contained in saidtnbular body which is made longer than the spring having hooks at itsends to provide 'for sliding engagement with the spring wherebyextension of the spring is limited.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
